built-in tar-tree and remote tar-tree
This makes tar-tree a built-in. As an added bonus, you can now say: git tar-tree --remote=remote-repository <ent> [<base>] This does not work with git-daemon yet, but should work with localhost and git over ssh transports. Signed-off-by: Junio C Hamano <junkio@cox.net>
